A Love Letter to the Korg iMS-20
Somewhat surprising to me, after finally getting a new iPad to replace an “ancient too soon” iPad 2, I found myself using the first iOS synth app I ever purchased more than the rest of my iOS music app collection – old or new. Simply put, the Korg iMS-20 simply serves my current musical needs more than the others.

Granted, I still haven’t picked up the Moog Model 15 app. That one is coming soon. I’ve played a bit with Audulus 3; enjoy Korg’s ODYSSEYi, and wrote new loops on Rebirth and the iPolysix. Still, the iMS-20 resonates with me. So, here’s another love letter.

Fewer Options lead to More Inspiration?

There’s not even a published iMS-20 review here at TabMuse, as I had already moved on to newer apps by the time this website started. I still loved creating drum and bass loops with it, followed by additional composition and overdubs. The title track from Church of Hed’s Electric Sepulcher album and the cut Transaxiom, from the Autumn Shrine EP, both feature the iMS-20.

Great sound and a classic skeuomorphic interface make it easy to dive right in and create beats. The limitations of the iMS-20 – one monophonic synth and a drum machine – are compatible with a desire to use the app for beatmaking, knowing the overdubbing of other tracks using hardware and software synths comes next.

Despite creating a few beats in Korg Gadget, that app’s larger sound seems more appropriate for building a full production within the app, which isn’t normally the way I work. Thus, I don’t have anything released with a Gadget beat. Maybe someday, as it remains a great app.

By the way, it is possible to get additional melodic content out of the iMS-20 by using a tonal sound in one of the drum machine tracks and programming a melody with the sequencer. Is this yet another case of limitations leading to inspiration?

I Dream of Virtual Wires

As a virtual simulation of the classic Korg MS-20, the iMS-20 features a patch bay, making it possible to modify the synth sound using virtual cables. Sequencer patching is necessary for composing beats in odd time-signatures as well. Creating polyrhythmic patterns in this manner is a breeze, and something I want to explore further on upcoming projects.

Two Kaoss Pads enable the real-time manipulation of the included effects, synth parameters, and even sequencer melodies and patterns. Many times, instead of rendering the audio of an iMS-20 project and loading into the Pro Tools, I’ll just do a live performance into the DAW using outboard effects along with the virtual Kaoss Pads. This creates something warmer and more sonically interesting as a basis for further composition and overdubs.

One of the best beats the Muse recently delivered to the studio involves the iMS-20, so she obviously prefers it as well. Expect to hear the track that grew around this beat on a future release, along with others sure to come. Ultimately, when I wake up in the morning to compose a beat, while still showing love for the street, I reach for the Korg iMS-20.

Korg Gadget, Stroke Machine, and Thor all get Important iOS Updates
In the past two weeks, three of the leading iOS music apps received vital updates that significantly enhance their functionality. If you want to learn more about Korg Gadget, Stroke Machine, and Thor, check out our previous articles here at TabMuse. Read on further to get the latest news about these updates.

Korg Gadget adds Landscape Mode, Ableton Live Support, Two New Gadgets

Two new gadgets highlight the recent update to Korg’s Gadget beatmaker app. Unfortunately, Abu Dhabi and Bilbao are only available through in-app purchase, and are priced a bit too high at $9.99 each. For an app — already including 15 gadgets — that normally costs $40, $4.99 makes much more sense as a price point for an individual gadget.

Korg Gadget is a natural in landscape mode, one of the nice changes in its latest update. Screenshot by Author.

The new gadgets are suitable for anyone using samples in their music. Abu Dhabi is a cool looking beat slicer, and Bilbao is sample player that follows the same mapping as Gadget’s London drum machine, making it easy to swap out one for the other in a project. Surprisingly, Bilbao has no capabilities to use a mic to record samples on the fly — an oversight by Korg. Both gadgets allow the importing of your own samples.

Support for landscape mode is a great addition. Considering my affinity for Korg’s iPolysix and iMS-20 apps, the original portrait-only orientation of Gadget never felt quite right. It’s easy to switch between the two using the accelerometer.

Other enhancements in this Gadget update include upgraded support for external MIDI controllers — something I can’t wait to check out once I get a new iPad. (The 30-pin connector in my iPad 2 only works for charging these days.) Korg also added integration with Ableton Live, making it easy to port projects from Gadget to Live. Native 64-bit audio support rounds out the new features.

Stroke Machine wears the iOS Drum Machine Mantle

Wolfram Franke has been burning the midnight oil and the result is version 2.0 of his incredibly deep iOS drum machine app, Stroke Machine. The ability to compose beats in any time signature known to beast is the big selling point of this update to me — not that I use them all. A pad screen allows you to play beats with a noticeable lack of latency sure to make Android owners extremely jealous.

Stroke Machine’s stability is also greatly improved; I regularly write beats with nary a glitch or crash. Still, this is a professional-level music app that gets the most out of the resource-constrained environment of the iPad, so iPad Air owners can expect to enjoy the best performance.

Audiobus 2.1 support allows the saving of kits and patterns within an AB patch. Fresh support for MIDI CC learn enhances the app’s use with external MIDI controllers. Additionally, each sound/voice can now use its own MIDI channel. Boom!

Thor also adds Audiobus 2.1 Support

The excellent iOS version of Thor, Propellerheads’ synth originally introduced as part of Reason, also received a fresh update recently. The most notable changes involve support for Inter App Audio and Audiobus 2.1. Now, like with Stroke Machine, Thor’s patch details can be stored as part of an Audiobus project. Other bug fixes and performance improvements come along for the ride.

So there you have it, three important updates sure to make music creation on an iPad more fun and rewarding. After watching a video of someone using Gadget’s Abu Dhabi beat slicer, I am inspired to check it out. When I do, expect a more detailed review here at TabMuse.

Review: Audulus brings the Modular Synth World to the iPad
iOS musicians interested in exploring modular synthesis on their iPad or iPhone need to check out the excellent app, Audulus. Featuring a clean, state-of-the-art user interface and great sound, Audulus does a nice job of scratching that sound design itch when a desktop or laptop computer running Reaktor isn’t available. A Mac OS X version lurks as well; someday I hope to check it out.

Audulus for the iPad Features
- Universal App Supports iPad and iPhone
- Excellent User Interface leveraging Vector Graphics and the Retina Display
- Many Modules, including Oscillators, Envelopes, Math, Filters, Effects, and More
- Monophonic and Polyphonic Support
- Build your Own Modules with an In-App Purchase
- iCloud Patch Sync between iOS and Mac Versions
- Support for MIDI, Virtual MIDI, and Audiobus (Input and Effect)
- Available at the App Store for $14.99
Audulus allows users a host of options for modular sound design framed in an easy to use interface that works nicely on the iPad. Interested synth tweakers take note.

Audulus shines on the Touchscreen

While the Audulus “paper” documentation is limited, there are a host of sample patches worthy of exploration. Developer Taylor Holiday also provides excellent tutorial videos that explain many of the app’s interface and module concepts. The included patch browser is easy to navigate.

Audulus nicely leverages iOS touchscreen gestures for app navigation. A press on the screen brings up circular styled context menus as needed. Zooming in and out works as expected.

Adding new modules and “wiring” them together is generally a breeze. A special connection mode makes wiring an easier process, especially when dealing with modules with tons of connections, like the 16-step sequencer.

I definitely recommend watching Taylor’s introductory video that walks you through creating a synth patch that utilizes a sample and hold module powered by a random number generator to give the sound a sense of motion. This becomes a great starting point for your own patches.

Also be sure to take advantage of Audulus’s meter modules to get a feel for what is happening in your patch. The tutorial videos do a nice job of explaining how these work and where they are useful.

Audiobus Effect Support Intrigues

In addition to synth patches, you can use Audulus to create effects for processing external audio. The app supports Audiobus, working as both an input and an effect, so audio from other iOS Audiobus compatible apps can be tweaked as well. This definitely improves the utility factor of the app.

Audulus’s sequencer module looks like one half of a millipede. Screenshot by Author.

Support for external MIDI keyboards and Virtual MIDI lets you control Audulus and its modules from alternate sources.

As mentioned earlier, Audulus’s non-video documentation, while helpful, serves more of a reference role. Additional written tutorials would be helpful. Having said that, this is an app where simply diving in and experimenting will be rewarded. The Audulus forums are a good place for help if you get stuck.

Special note must be given to Jody Golick’s four included patches that reveal the level of art possible with Audulus. The sounds and music they generate definitely inspire, but I wish the app’s labeling functionality was used to explain some of the patch design decisions. Maybe a tutorial wrapped around Golick’s work would be a nice addition?

This Audulus setup adds a sense of motion to a patch by controlling the cutoff frequency on a filter. Screenshot by Author.

Taylor Holiday continues to support Audulus with patch presets and sample audio support on the docket. Personally, I’d love a more fleshed-out sequencer module with a varying number of steps and support for direct note, key, and chord entry, as opposed to the current frequency entry. In the interim, the following frequency to note conversion website is a godsend.

There’s no denying that Audulus is a special achievement in the world of iOS music apps. A stunning user interface makes modular sound design a blast. I recommend this app for any iOS musician interested in exploring modular synthesis.

Review: The iVCS3 raises the Bar for iPad Hardware Emulation
The EMS VCS3 — with other models known as the Synthi or Putney — is a legendary analog synthesizer from the Golden Age. Pink Floyd’s “On the Run” from Dark Side of the Moon famously uses the VCS3, and that same synth arpeggiation now serves as the “Hello World” application for many current analog beatboxes, like the Korg Monotribe.

The iVCS3 app, developed by apeSoft, is the official EMS VCS emulator for the iPad, and frankly, this rich and detailed app raises the bar for analog synthesizer emulation. So there.

The iVCS3 for the iPad Features
- Three Oscillators (Two Main, One LFO)
- Noise Generator
- Two Amps, One Envelope, One VCF
- Virtual Patch Board Matrix, Joystick, and Keyboard
- Sequencer
- Audiobus 2.0 Support (Including State Saving)
- Inter App Audio Support
- Available at the iTunes App Store for $14.99
Like the hardware original, the iVCS3 is perfect for sound effects and processing external audio. It does function nicely as an Audiobus Effect, so the same use-case works on the iPad. The dead-on simulation of the VCS3’s unique hardware interface and wonderful sound make the app a must have for iPad synth aficionados.

A Richly Detailed iPad Synth App

Thankfully, the iVCS3 app comes with hundreds of patch presets, as the synth’s rich synthesizer architecture makes it a bit difficult to dive right in. The app includes copies of the original VCS3 synthesizer manual as well as the iOS version. Be prepared to spend some enjoyable time reading the original manual as well as perusing the collection of patches, which include some of Delia Derbyshire’s work for Doctor Who.

The iVCS3 is a dead-on simulation of the classic hardware original. Screenshot by Author.

The VCS3’s peculiar interface with its pin board patch matrix and joystick are nearly perfectly emulated on the iPad. As you navigate between the app’s three main screens (two for the synth and one for the sequencer and other functions), it is possible to bring the joystick along for some real-time patch tweaking. The virtual keyboard is similarly “portable.”

While deep, the architecture should be somewhat familiar to anybody who knows subtractive synthesis; the names of some of the parameters may have changed, but they work the same. The touchscreen operation of the knobs, switches, joystick, and patch matrix are all top notch; I wish all the knobs on iOS synth apps worked as well.

A Classic Emulation of Analog Sound

The sound of this app is stunning, hearkening back to the classic albums and science fiction TV shows of the early 70s. The VCS3 earned a reputation as a top notch synth for sound design instead of prog-like keyboard wizardry, and the iVCS3 is no exception. It is possible to lose hours playing around with the preset patches.

I was able to get cool results running some beats from DM1 into the iVCS3 with Audiobus, using the iVCS3’s filter and ring modulator circuitry. Once again, the preset patches were a godsend as far as getting things running. I’d recommend starting with a preset to make your own patches; wide varieties exist for most usage scenarios.

The iVCS3 app in action as an effect in an Audiobus session with DM1 providing the input. Screenshot by Author.

Speaking of presets, let’s talk about the data architecture around patches. The iVCS3 contains any number of banks which hold individual patches, called snapshots. It is possible to load 4 snapshots in each bank to the SnapPad, an X-Y controller that allows for real-time morphing between the snapshots — ala the Animoog.

The iVCS3 loves its Computing Power

Like many recent iOS music apps, the iVCS3 requires a fair amount of computing horsepower. It behaved mostly well on my iPad 2 with the latency set to 512 samples. Occasionally there were audio stutters, especially when switching between the synth and the sequencer. Apps like Korg Gadget, Stroke Machine, and iVCS3 have put an iPad Air in my future sooner than later.

The iVCS3 is a rich synth app with incredible sound and a stunning emulation of the unique hardware interface of an analog synth classic. Any musicians interested in vintage synths and edgy sound design need to head over to the App Store for a downloading session.

Korg Gadget — Reviewing the Synths, Part 2

So we’ve reviewed Korg’s powerful Gadget iOS beatmaking app; we covered its drum modules, and the first half of its synth collection. Naturally, what follows is a look at the other six synth modules of Gadget. Expect these Gadgets to be useful for creating a wide range of electronic and esoteric music.

Wolfsburg offers a Distant Mirror to 80s Polyphony

Wolfsburg is essentially a mini Rompler filled with sampled waveforms from a variety of classic analog synths. The sounds seem more 80s oriented than related to the 70s, with classic Oberheim and one can assume the Korg Polysix and Poly 61 well represented. Its main difference with Phoenix is being sample-based versus the latter’s virtual analog emulation.

Two oscillators operate in either monophonic or polyphonic modes. Noise can also be mixed into the equation. A standard array of subtractive synthesis controls (including a filter), a useful modulation matrix, and two separate effects round out Wolfsburg.

Brussels spouting Today’s Monophonic Anthems

A unique monophonic Gadget with a host of modern musical applications, Brussels serves well as either a lead or bass instrument. The “Anthem” moniker definitely applies. Brussels sports a modern, sleek interface with a collection of interesting synth controls organized within three sections: Generator, Performer, and Output.

The Performer section’s pump and repeat controls appear to influence a patch’s delay and envelope settings — more or less. The interface lends itself to experimentation, especially the Generator section which offers unique tweaking of the filter, glide, and low-end controls. The Output section includes a reverb as Brussels’ only true effect.

Kiev resides in Outer Space

When a track needs a bit of ambience to finish it off, or if you are creating a music piece squarely in the realm of outer space — Kiev is the Gadget of choice. An “Advanced Spatial Digital Synthesizer,” Kiev is slightly reminiscent of Animoog. It uses four waveform oscillators, leveraging an x-y pad to mix the four in real time.

Korg Gadget’s Kiev is squarely in outer space. Screenshot by Author.

A second screen provides access to a filter, envelopes for the amp and filter, and a singular multi-effect. This is a fun, spacey Gadget suitable for real-time tweaking. Hopefully some additional waveforms get added in a future update (or the ability to load your own), but there are currently enough to satisfy most musical scenarios.

Chiang Mai for Take Out

Chiang Mai is a Gadget sporting a variable phase modulation architecture. This makes it suitable for bells, organs, or even a decent lead. Some of the factory presets cover basses and even sound effects pads — it’s a pretty versatile gadget with a DX-like sound.

The first screen offers access to the oscillators and filter; be sure to tweak the harmonics control on both oscillators to get a feel for the sonic possibilities. The two envelopes as well as chorus and delay effects reside on the second screen. If you want to channel those crystal clear sounds of Yamaha in the 80s — Chiang Mai is your Gadget.

Taking our Talents to Miami

Looking for a modern sounding low-end? Check out Miami. This unique monophonic gadget offers an interesting architecture not unlike Brussels with the Wobble knob — a form of BPM synced LFO — taking center stage. Miami is also suitable for some badass lead sounds as well.

Miami’s filter has a resonance control called “Crush” suitable for an extra edge compared to other filters. The carrier and “X-Mod” dual oscillator setup is capable of some complex waveforms. I’d like a delay (wouldn’t we all) but the Wobble function almost serves that role.

Helsinki brings Scandinavian Ambience to Gadget

Another Gadget suitable for ambience, Helsinki rounds out Korg’s collection of virtual sound modules. The interface even hints at an icy Scandinavian winter and the sounds come pretty close as well. Many useful drones or mellow leads lurk within.

The Helsinki architecture utilizes a generator that combines an oscillator with an EQ; noise can also be mixed in. The LoFi frequency control is great for real-time tweaking. A filter, envelope, and a reverb finish off Helsinki.

There you have it — twelve great Gadgets and an environment for electronic music creation provided by Korg all within one app. Gadget is simply a must download for iPad musicians. Hopefully future updates with add to the mayhem — especially a new drum module or three!

Review: microTera — Waveshaping the iPad Synth World
VirSyn’s microTera is an excellent iPad synth app that offers its own take on the world of iPad sound creation. Essentially a smaller version of the miniTera desktop softsynth, which I used on Church of Hed’s Rivers of Asphalt album (“Painted Desert and Mountain Sky“), microTera features an intuitive interface with a unique and powerful synth architecture based on waveshaping. A top notch sequencer/arpeggiator and a robust effects engine round out the package.

microTera for the iPad Features
- Waveshaping Synthesis with a Touchscreen Control
- Three Sine Oscillators
- Four LFOs and Four EGs with Tempo Sync
- 16 Voices either Monophonic or Polyphonic
- Programmable Sequencer and Arpeggiator
- Five Effects (Chorus, Phaser, Distortion, Delay, Reverb)
- 150 Factory Patches
- Support for Audiobus, Inter App Audio, CoreMIDI, Virtual MIDI, and more
- Available at the iTunes App Store for $9.99
microTera’s unique synth engine positions it as a standout in the crowded iPad synth app scene. The powerful sequencer and graphical waveshaping interface make this app a must download for synth fans.

Waveshaping Synthesis for the Masses

microTera’s interface is spread across four main screens, covering waveshaping, envelopes, arpeggiator, and effects. A menu bar at the top navigates between the screens along with providing patch management and other functionality. A functional touchscreen keyboard lies at the bottom of the interface.

microTera’s waveshaper interface offers an intuitive touch-enabled interface. Screenshot by author.

Clicking on the pair of dice in the top menu bar randomizes a patch, offering a great way to dive into the microTera’s unique synthesizer architecture. Just tap and go.

microTera features three sine oscillators that get fed into the waveshaper. Detuning the oscillators against each other creates interesting harmonics and noise in the waveshaper, which also sports a graphical display that can be manipulated in real time. The Chaos level knob introduces noise using a feedback loop, adding to the general sonic mayhem.

Envelopes, LFOs, and a Modulation Matrix

Four envelopes, each with an intuitive graphical touch interface, help to make patches breathe. A simple modulation matrix is built into the waveshaping screen, providing control of the oscillators, waveshaper input, Chaos level, amplitude, and panning. It’s a powerful setup.

In addition to using the envelopes as modulation sources, microTera also provides four LFOs able to join in the fun. Each LFO is syncable, with a standard selection of waveforms. Other modulation sources include pitch, velocity, aftertouch, mod wheel, pitch bend, and more.

Effects added to the Mix

microTera’s architecture has five separate effects each powered by an intuitive interface. The phaser especially provides a nice sheen, and the BPM-synced delay adds another measure of motion to synth patches. The distortion effect includes both tape and tube options.

microTera’s effects engine adds nicely to the sonic mayhem. Screenshot by author.

The chorus and reverb serve well in providing patches with a sense of space as well as creamy sonics. My only real complaint about the effects is that their parameters apparently can’t be modulated.

An Intuitive and Powerful Arpeggiator

microTera’s powerful arpeggiator is one of the best available for an iPad synth. Effectively a sequencer, it is possible to easily create patterns of up to 32 steps with control over notes, accents, and more by using finger swipes (take note Cakewalk Z3TA+). Yes Virginia, odd time signatures are possible.

microTera’s powerful arpeggiator provides the icing on the cake for this excellent synth app. Screenshot by author.

Pairs of dice lurk all over the interface, meaning most everything in the arpeggiator can be randomized. Your patterns are savable which is especially useful when randomizing patches on the fly. This combination arpeggiator and sequencer serves as the final piece of the puzzle, making microTera one of the top synth apps for the iPad.

Don’t let your unfamiliarity with waveshaping synthesis scare you from picking up microTera. The patch randomization feature and easy to follow interface make creating your own patches a breeze. Throw in one of the best arpeggiators on the iOS platform, and it becomes easy to recommend microTera.

Korg Gadget — Reviewing the Drum Modules

Korg’s “studio-in-a-tablet” app, Gadget, continues to amaze with its intuitive interface and versatile collection of sound-producing “gadgets.” We previously gave Gadget a positive review, and also took a closer look at one half of its synth collection followed by the other half.

What follows in this article is a more detailed analysis of Gadget’s three drum modules. Well, it’s really more like two-and-a-half, as Amsterdam provides a full range of sound effects, pads, and hits in addition to some drum sounds — ultimately, it fits better in this article. Hopefully, more drum modules get added in a future Gadget update.

London calling out PCM Drum Beats

London is Gadget’s main drum module. It offers a host of PCM sounds — over 400 — geared towards the dance beat creation scene. The gadget includes three main screens used for editing, fine tuning of effects, and mixing.

London is Gadget’s go to drum module featuring PCM sounds. Screenshot by author.

You can edit each of the eight voices’ pitch as well as switch between a gate and a one-shot envelope using a knob to control the release time. There’s one master effect for each drum patch, with each individual voice also providing punch and low boost controls. The mixer offers the standard pan and level functionality by voice.

London is a solid PCM drum module and the lack of many other alternatives means it needs to be used on most non-ambient tracks created in Gadget.

Tokyo goes Virtual Analog Percussion

Tokyo offers great-sounding virtual modeled analog drum sounds and an effective modular-like interface. Frankly, I wish it provided more than four voices — maybe a six or eight voice version would be included in a future Gadget update? It especially works well when enhancing the PCM sounds coming out of London.

Tokyo brings virtual analog drum sounds to the Gadget equation. Screenshot by author.

The four modules within Tokyo are geared towards creating kick, snare, tom, and percussion sounds respectively, but strategic knob-twiddling makes it possible to conjure up some interesting effects. Each module sports similar controls, like Tune and Decay; the differences between the four warrant additional experimentation. A master effect at the patch level rounds out Tokyo’s sonic design.

A Boombox in Amsterdam

Korg calls Amsterdam a PCM SFX Boombox, and its funky interface definitely looks the part. A wide array of sounds, effects, and musical pads lurk within. There are four different voices, making it possible to program simple chord progressions or a collage of sound effects.

Amsterdam is a versatile module, giving Gadget a wide range of drum sounds, effects, and even musical pads. Screenshot by author.

Amsterdam’s one screen includes a mixer, tuning and envelope control for each sound, and controls for the master effects. The ability to load one’s own samples would be a really great addition to Amsterdam in a future update. Still, the included sound set offers a good measure of sonic versatility.

Well that’s it. Considering the robust collection of synth modules, the inclusion of so few on the drumming side of the shop is arguably Gadget’s biggest weakness. All three modules have their unique strengths and will serve you well in your own beatmaking exercises.

My biggest hope is that future updates mean more percussion sound options — in addition to more voices for Tokyo. That latter point is made as an iPad 2 owner who can only run a limited number of gadgets at one time!

Review: Z3TA+ is a Cakewalk among iPad Synth Apps
First earning fame as a plug-in for Cakewalk’s Sonar DAW software, Z3TA+ recently saw its debut on the iOS platform. This incredibly deep synthesizer immediately becomes one the most powerful music apps on the iPad. Featuring a robust synth architecture and a ton of useful features, Z3TA+ is a must get for the iOS musician.

Z3TA+ for the iPad Features
- Synth Architecture includes 6 Waveshaping Oscillators
- 6 LFOs, Rich Envelope Generators and Filters
- Robust Modulation Matrix and Effect Engine
- Powerful Arpeggiator with over 250 MIDI Patterns and Gates
- Touchscreen Functionality include X-Y Pads and Virtual Keyboard
- Support for Audiobus and Inter App Audio
- Available at the App Store for $19.99
Z3TA+ establishes itself as one of the top iPad synth apps, up there with Waldorf Nave, Propellerhead Thor, and the Animoog. A clear user interface with three main pages helps the understanding of the synth’s operation. Its deep feature set and great sound quality will make it an important part of any musicians’ tablet synth arsenal.

Z3TA+’s Detailed Synthesizer Architecture

The core of Z3TA+’s synth architecture is made up of six independent oscillators each capable of a robust number of waveforms. A graphical waveshaping interface on the iPad’s touchscreen adds to the fun. Each oscillator also sports a multimode spawning eight more oscillators for a total of 48, but make sure you have a newer iPad model as this uses up CPU power.

Reverse engineering any of the 500 presets is the best way to figure the best oscillator combinations — a standard practice with any synth — but supremely useful given all the options of the Z3TA+. The synth architecture also includes six LFOs and six EGs which really come into play with Z3TA+s convenient modulation matrix.

Two filters are capable of dual or parallel operation with a host of standard filter types and some more esoteric options like comb or formant. A collection of automatable controls for all synth sections (OSC, LFO, EG, and Filter) rounds out Z3TA+’s main synth page.

A Powerful Modulation Matrix and Arpeggiator

Z3TA+’s modulation matrix reminds me of Thor, offering up to 16 sources and destinations to truly leverage the synth’s detailed architecture, especially the six LFOs and EGs. The matrix’s range parameter is controllable with a finger swipe — a convenient use of the touchscreen interface. Once again, reverse engineering one of the app’s many presets is a great way to get modulation ideas for your own patches.

The powerful arpeggiator sports over 250 MIDI patterns and gates in addition to the standard arpeggios. Hopefully, the ability to program your own patterns is added in an update. I found my fingers drawn to the arpeggiator interface hoping to change things up. I don’t know if this capability exists in the desktop version of Z3TA+?

A Robust Effects Engine

Z3TA+’s effects engine finds its home in the app’s third main page. A whole host of effects are included, most notably three independent delays. The Mod effect includes a variety of choruses, flangers, and phasers.

Z3TA+ for the iPad features a robust effects engine. Screenshot by author.

Most effects parameters can be used as destinations on the modulation matrix, and their controls are automatable. Check out the little routing sub-page which allows for changing how the effects connect to each other using drag and drop. This is a nice touch!

Z3TA+ definitely establishes Cakewalk on the iOS platform. This is a stunningly deep and powerful synth capable of a wide array of sounds suitable for electronic music and beyond. It deserves our highest recommendation, belonging in the library of any synth aficionado with an iPad.

Korg Gadget: Reviewing the Synths — Part 1

Korg’s recent release of Gadget gives iPad musicians something similar to Propellerhead Reason on a tablet computer. Last week’s Gadget update added support for Audiobus. With 15 different gadgets — each essentially the equivalent of a separate iPad synth app — the amount of sonic possibilities can get overwhelming.

With that in mind, let’s take a closer look at six of the synths included in Korg Gadget. Future articles will cover the other six synths and Gadget’s three drum machines. Note that all the gadgets are named after cities.

The PCM Synthesis of Marseille

A PCM playback synth, Marseille arguably offers the most robust collection of sounds within Gadget. Its organization of patches is pretty similar to the General MIDI standard. The virtual keyboard allows for one-touch chord play which serves well for real-time loop sequencing when paired with one of the many pad patches.

Two effects — each with knob-twiddled control of two parameters — and an ADSR envelope round out Marseille. Expect this synth module to provide a measure of sonic versatility to many Gadget creations.

Chicago brings that TB-303 Flavor

If you are looking for that classic acid bass sound for your project, Chicago makes a great choice. Even its shiny metallic interface is reminiscent of the Roland TB-303. A host of automatable controls — including the all important filter cutoff and peak — add to the utility of this gadget.

A basic arpeggiator makes creating quick bass lines a bit more convenient. One effect includes everything from reverbs and delays to a ring modulator and decimator. A virtual tube amp controlled by either a gate or an ADSR envelope finishes off the sonic stew.

The Virtual Patch Cords of Dublin

Another gadget offering quality bass sounds among other classic virtual analog tones is Dublin. Its wood-grained interface even adds a patch bay, putting pseudo-modular sonic exploration within touch. The control layout feels Moog-like, with the VCO, VCF, VCA, and Mixer sections located where they should be; a button press switches between the synth and patch bay sections.

Drive and Tone controls are Dublin’s only effects, but the added functionality of the patch bay makes up for the absence of multi-effects. Dublin should please aficionados of classic electronic music, but probably not Irish music fans.

Phoenix provides Polyphonic Analog Sounds

Folks who love those classic polyphonic analog sounds of the 80s need to explore Phoenix. This gadget seems to fit somewhere between the Oberheim line and Korg’s own Polysix. The easy-to-follow interface has separate panels for the synth and modulation controls.

While a delay is the only effect type for this gadget, it is useful in giving some of the patches life. My only complaint is wishing Phoenix provided the one touch chord play feature as with Marseille.

Gadget goes to Berlin School

While you can go “Berlin School” by using Dublin, Berlin is another worthy source of bass or lead synth mayhem. Its interface reminds one of the early 70s ARP synths but more closely the Electro-Harmonix Mini Synthesizer (which I sadly lost many years ago). Berlin’s monophonic, sync-modulated sound bites through a dense mix, making it especially useful as a lead synth.

The EH-inspired controls are split into two panels covering the VCO/modulation and the VCF/VCA. A delay is the only effect, but a vibrato adds to Berlin’s sonic footprint. The nasally low pass filter is pretty cool as well.

Kingston: Home for the 8-Bit Chip Tune?

Who knew Kingston, Jamaica was the home for 8-bit chip tune music? Well not really, but Kingston is a gadget offering those classic blips and beeps of the NES music scene. Its interface even looks more like an arcade game than an old-school analog synth.

I don’t imagine using Kingston too much in my projects, but it makes a great gadget for anyone interested in getting their 8-bit mojo on. Well, maybe some of those low-fi outer space sounds would work in a Spacerock tune!

Review: Korg Gadget gives Reason to iPad Beatmaking
Korg’s new Gadget app for the iPad is a fully-fledged beatmaking environment featuring up to 15 different synth and drum machine modules usable simultaneously. Essentially this is Reason on a tablet. The app’s sound quality is great, and Gadget also sports a robust feature set that makes it a breeze to create music.

Korg Gadget for the iPad Features
- 15 Separate Instrument Modules (Synths and Drum Machines)
- Easy-to-use Portrait Oriented Interface
- Multiple Time Signatures
- Synth, Drum Machine, and Mixer Effects
- Easily Record Control Automation
- Support for AudioCopy and WIST
- Export Audio to GadgetCloud Service powered by SoundCloud
- Available at the App Store for $28.99 (Regular $38.99)
Korg Gadget is a great “go to” app for tablet-based beat construction. Users with recent iPad models can really crank up the number of the simultaneous tracks — up to 25 on the iPad Air. It is a must have download for iPad owners interested in electronic music creation.

15 Gadgets for You and You and You

Gadget’s collection of 15 synth and drum machine modules features something for nearly all musical tastes. Everything from the TB-303 inspired bass synth, Chicago, to the monophonic “modular” synth, Dublin, inspires creativity. Each gadget is named after a city, for what it’s worth.

The 12 synth modules are enough to support most musical styles, especially when considering the huge array of sounds in the PCM-based gadget, Marseille. I would have preferred another drum machine or two, since there are only three in the app. Korg is planning on releasing new gadgets in the future, probably through an in-app purchase.

Each gadget features an attractive on-screen interface with all the relevant automatable controls, including virtual patch cables for Dublin. On some gadgets, an on-screen keyboard provides the typical touchscreen playing functionality, like one-finger chords and built-in scales. Each gadget comes with either one or two effects to further tailor the sound.

Expect future TabMuse articles to profile Gadget’s robust collection of synths (Part 1 and Part 2) and drum machines more deeply.

A Sequencer that’s a Breeze to Use

Gadget’s sequencer easily allows for either real-time or step-based beat creation. The app uses a portrait oriented interface, with the top half focusing on the sequencer and the bottom half controlling either a mixer or an individual gadget. The intuitive interface is a breeze to use.

Each song is made up of any number of scenes which can vary in length and time signature individually — a great feature! Scene and track management is an easy process; so is sequencing the parts of an individual track. Control automation is accomplished through either real-time knob twiddling, or after the fact envelope drawing.

The mixer is also automatable with a standard set of volume and pan controls. Two song-level effects (Limiter and Reverb) are useful for mastering a final mix.

While my iPad 2 is only limited to 5 tracks in Gadget, that isn’t a real bother for me as I’ll dump a beat into ProTools for additional overdubs and melodic development. Those of you with newer iPads can really go to town, with over 20 tracks possible on Apple’s newer tablets.

Korg Gadget offers a ton of synth choices and host of features making its high price well worth it for iPad musicians. This app ranks with the Korg iPolysix, and easily earns my highest recommendation. Check out these profiles of six of the gadgets and the three drum modules within Korg’s innovative iOS app.
